Effect of agrotechnical and chemical practices on Fusarium rot root in sugar beet production

Sugar beet is one of the economically significant industrial crops for the south and southeast of Kazakhstan. In the conditions of Kazakhstan, the best predecessors of sugar beet are winter wheat and alfalfa, which contribute to the improvement of the susceptibility of beet rot. Early plowing by the semi-pair type in the second decade of August allows reducing the susceptibility of root crops to Fusarium rot by 18%. It is shown that 6 centner/ha of wheat straw on the artificial background contributed to decrease in the prevalence of Fusarium rot, on average 1.4 times, Rhizoctoniosis rot – 1.2 times compared with the control. Increasing the rate of nitrogen and phosphate fertilizers contribute to the development of root rot (2-3 times) of sugar beet. To reduce the severity of rotten root crops (from 1.3 to 2.5 times), 6 t/ha of wheat straw are proposed to be applied to the soil together with N90P75K70. Seed treatment with tachigaren seed, rovral and fundazol reduces the development of rot by 8.1-16.6% and leads to an increase in yield of root crops by 31.5-50.2 c/ha.

The Prestige

The effectiveness of the insecticofungicide Prestige, KS, used to protect plants from damage by diseases and damage by pests in the first stages of ontogenesis is shown. Presowing seed treatment with a preparation with a flow rate of 2.5–3.5 l/t reduced the incidence of winter wheat with root rot of rhizoctoniosis etiology by 62.9%. The biological effectiveness of the Prestige, KS (3.5 l / t) on moderately infectious background was also quite high - 59.5%, however, it was 9.0% lower than the standard. It practically did not influence overwintering of plants. After application of Prestige, KS were in the norm of 2.5 and 3.5 l/t, and Maxim Extreme, KS in the norm of 1.75 l/t, the number of plants preserved by spring varied from 91.9 to 92.9%, that is higher than in the control by 3.9–4.9%. The application of insectofungicide Prestige, KS at a rate of 2.5 l/t on spring wheat sowings reduced the number of grain fleas by more than 80.0%and the damage of the stems by the larvae of cereal flies by 74.3%. This preparation is not phytotoxic with respect to cereals.

Plant Samples

The aim of this study was to determine the oomycetous pathogens causing root rot on sugar beet and test their control by seed treatment in Konya Province, Turkey. Oomycetous fungus-like pathogens of sugar beet were investigated using 866 plant samples collected at 2 growth stages, early seedling and late root, from fields in the Konya region of Turkey and 1 sample from the Thrace region. Herein, 10 oomycetous species belonging to 3 genera: Aphanomyces cochlioides, Phytophthora cryptogea, Ph. pseudocryptogea, Ph. megasperma, Ph. inundata, Pythium aphanidermatum, Py. helicoides, Py. heterothallicum, Py. sylvaticum, and Py. ultimum var. ultimum (Globisporangium ultimum var. ultimum) were discovered at various times with in the 2 growth periods, all of which were the first records for Turkey. A. cochlioides was the most serious pathogen, both in terms of its wide distribution and aggressiveness. The pathogen produced more than 90% disease severity when tested by soil infestation at the seedling stage, although it also occurred at the late root growth stage. Pythium species were also ascommon, such as A. cochlioides, the majority of which were very aggressive, producing more than 84% disease severity at the seedling stage, except for Py. aphanidermatum. Half-strength potato dextrose agar medium was found to be very useful for the isolation of all of the pathogens from the plant samples at both stages. Morphological features of all of the pathogens were abundantly produced when the pathogens were grown on amended grated carrot agar medium and culture disks of fungal growth of this medium were submerged in sterile and nonsterile soil extracts. Out of the 15 fungicide mixes tested, 2 mixes, thiram+metalaxyl+hymexazole and thiram+metalaxyl+hymexazole+ pyraclostrobin reduced seedling root rot caused by both A. cochlioides and Pythium ultimum var. ultimum, while the standard seed treatment fungicide mix of thiram+hymexazole was not effective against either of the pathogens.

Purpose. Establish the impact of basic tillage and weed protection measures on soil density in winter wheat and sugar beet crops. Investigate the criteria for the formation of winter wheat and sugar beet productivity depending on weather conditions, measures of basic tillage and protection against weeds. Methods. Field, laboratory. Results. Soil density for the period of winter wheat harvesting for plowing to a depth of 20–22 cm and direct sowing was in the same range at the level of 1.22 and 1.23 g/cm3, which can be explained by the peculiarity of the soil and the root system of the plants themselves. In sugar beet crops, the combination of plowing to a depth of 25–27 cm with subsequent shelfless loosening at 34–36 cm makes it possible to maintain the density of the arable soil at the level of equilibrium for this type of soil. In other treatments, the soil density increases to 1.27 and 1.28 g/cm3, with compaction of the upper 0–10 cm layer of soil to 1.25 g/cm3 for plowing by 30–32 cm and 1.29 g/cm3 – for shelf-free loosening by 34–36 cm, which has a negative impact on the productivity of sugar beets. Conclusions. With the optimal sowing period for the conditions of Kyiv region on September 12–15, the most optimal sowing rate remains 4.5 million units. nas./ha, for increase in density of standing of plants we note lodging of plants and damp years and essential shortage of grain in arid. According to our research, the main tillage for winter wheat plowing by 20–22 cm remains the most rational for obtaining stable yields of winter wheat (yield was 5.03 t/ha). At the same time, good predecessors of peas for grain, rape, buckwheat can be used direct sowing with the introduction of herbicide continuous action Roundup, 48% v.r. 3.0 l/ha. The highest productivity of sugar beets was obtained by using the main tillage plowing by 25–27 cm + shelfless loosening by 34–36 cm yield of root crops at the level of 52.13–51.73 t/ha, sugar content – 14.80–14.83%, sugar harvest – 7.73–7.81 t/ha. On deep medium loam chernozems, this tillage allows to ensure optimal agrophysical indicators of the soil, remove the plow sole, earn crop residues and ensure yields in arid conditions. Application of sugar-free loosening to sugar beets to a depth of 34–36 cm reduces the yield of root crops by 5.32 and 7.20 t/ha compared to plowing to a depth of 30–32 cm, which is associated with an increase in weediness of crops and soil density.

The Republic

The effect of application of the Albit preparation during autumn spraying in pure form and in a mixture with fungicides was studied. It was found that the use of Albit promotes the growth of plant conservation during wintering of wheat plants and reduces the root rot development of winter wheat. In combination with benzimidazole fungicides this effect was enhanced. The maximum crop productivity - 3.75 tons per hectare was in the use of Albit + Ferezyme mixture in combination with Vial Trust seed treatment. As a result of the use of Albit, there was an increase in the content of gluten in the grain. The use of this method has increased the economic efficiency of wheat cultivation.
